CBSE class 10 Science - Sources of energy - There are two types of energy sources : Renewable Sources of Energy and Non-Renewable Sources of Energy. Renewable energy can be regenerated and are also called as the in-exhaustible sources of energy. Non-Renewable energy is reserved and can not be made again and are also called as the exhaustible sources.

Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.

Natural resources can be classified as renewable and nonrenewable resources. Natural resources can be classified as renewable or nonrenewable
A renewable resource can be replaced at the same rate in which the resource is used
Common renewable resources used to produce energy include,
Solar, like these solar panels converting solar energy into electricity. A nonrenewable resource is a resource that forms at a rate that is much slower than the rate that it is formed. Coal is an example. It takes millions of years to create coal and once it is used up it is no longer available
You can use CON to remember three popular nonrenewable resources.
This stands for
Coal
Oil
Natural Gas
#sciencevideo #msscience #sciencehelp

The difference between renewable and non-renewable resources can be done on the basis of their usage life, carbon emission, quantity available, maintenance cost, environment friendly nature, land area required for installation and much more.
The energy resources which cannot be exhausted and can be used again and again are called renewable energy resources. For example solar energy, wind energy, tidal energy and hydroelectric etc.
The energy resources which can be exhausted one day and cannot be used repeatedly are called non-renewable energy resources. The example of non-renewable energy resources are coal, petroleum, natural gases etc.
1. The renewable energy resources can be depleted and used again and again. But the non-renewable resources are limited in number and can be depleted one day.
2. The carbon emission in renewable energy resources are very low and prevent global warming. In non renewable resources the carbon emission is large and contributes in global warming.
3.The renewable resources are cheaper and present in unlimited quantity but the non- renewable resources are costlier and present in limited quantity.
4. The life of renewable resources is infinite. In case of non-renewable resources the life is finite.
5. The maintenance cost for the power plant of renewable energy resources is low but it is high in the case of non-renewable energy resources.
6. Solar energy, wind energy, tidal energy and geothermal energy are called as renewable resources. Coal petroleum, natural gas, are called non-renewable resources.

This video shows presentation with question "Define renewable energy. State four types of renewable source of energy and discuss the advantage and disadvantages of each type"

This video represents a good explanation of What is energy for kids. You will gonna learn about Energy Sources for kids, How we use Energy ( how to save energy ) and a brief understanding about different types of Renewable Energy resources as well as the nonrenewable ones.
► What is energy ?
The best definition of energy, that every children should know, is that the Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. We use energy to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, and to light our homes. Energy comes in different forms:
Heat (thermal), Light (radiant), Motion (kinetic), Electrical, Chemical, Nuclear energy and Gravitational Energy.
People use energy for everything from making a jump shot to sending astronauts into space.
There are two types of energy: ( Stored (potential) energy + Working (kinetic) energy ).
For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play.
Energy sources can be categorized as renewable or nonrenewable
When people use electricity in their homes, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant on a river, to name just a few sources. Therefore, coal, nuclear, and hydro are called energy sources. When people fill up a gas tank, the source might be petroleum refined from crude oil or ethanol made by growing and processing corn.
Energy sources are divided into two groups:
1- Renewable (an energy source that can be easily replenished)
2- Nonrenewable (an energy source that cannot be easily replenished).
► Renewable energy and nonrenewable energy for kids :
Renewable and nonrenewable energy sources can be used as primary energy sources to produce useful energy such as heat or used to produce secondary energy sources such as electricity.
When people use electricity in their homes, the electrical power was probably generated from burning coal or natural gas, a nuclear reaction, or a hydroelectric plant on a river, to name a few possible energy sources. The gasoline people use to fuel their cars is made from crude oil (nonrenewable energy) and may contain a bio-fuel (renewable energy) like ethanol, which is made from processed corn.
► Moreover, you will gonna learn What is renewable energy for kids ?
There are five main renewable energy sources:
1- Solar energy from the sun
2- Geothermal energy from heat inside the earth
3- Wind energy
4- Biomass from plants
5- Hydro power from flowing water
► What is Nonrenewable energy ?
Most of the energy consumed in the United States is from nonrenewable energy sources: ( Petroleum products - Hydrocarbon gas liquids - Natural gas - Coal - Nuclear energy ).
Crude oil, natural gas, and coal are called fossil fuels because they were formed over millions of years by the action of heat from the earth's core and pressure from rock and soil on the remains (or fossils) of dead plants and creatures like microscopic diatoms. Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal.
Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity.
By watching this video, you will gonna learn how to conserve energy resources ( energy saving ) by understanding how energy conservation mechanism work as well as much knowledge about alternative energy resources. Enjoy watching and have a great time learning about energy sources for children.

What is SUSTAINABLE ENERGY? What does SUSTAINABLE ENERGY mean? SUSTAINABLE ENERGY meaning - SUSTAINABLE ENERGY definition - SUSTAINABLE ENERGY explanation.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
Sustainable energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.
Technologies that promote sustainable energy include renewable energy sources, such as hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bioenergy, tidal power and also technologies designed to improve energy efficiency. Costs have fallen dramatically in recent years, and continue to fall. Most of these technologies are either economically competitive or close to being so. Increasingly, effective government policies support investor confidence and these markets are expanding. Considerable progress is being made in the energy transition from fossil fuels to ecologically sustainable systems, to the point where many studies support 100% renewable energy.
Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy. Some ways in which sustainable energy has been defined are:
1. "Effectively, the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their own needs. ...Sustainable Energy has two key components: renewable energy and energy efficiency." – Renewable Energy and Efficiency Partnership (British)
2. "Dynamic harmony between equitable availability of energy-intensive goods and services to all people and the preservation of the earth for future generations." And, "The solution will lie in finding sustainable energy sources and more efficient means of converting and utilizing energy." – Sustainable Energy by J. W. Tester, et al., from MIT Press.
3. "Any energy generation, efficiency and conservation source where: Resources are available to enable massive scaling to become a significant portion of energy generation, long term, preferably 100 years.." – Invest, a green technology non-profit organization.
4. "Energy which is replenishable within a human lifetime and causes no long-term damage to the environment." – Jamaica Sustainable Development Network
This sets sustainable energy apart from other renewable energy terminology such as alternative energy by focusing on the ability of an energy source to continue providing energy. Sustainable energy can produce some pollution of the environment, as long as it is not sufficient to prohibit heavy use of the source for an indefinite amount of time. Sustainable energy is also distinct from low-carbon energy, which is sustainable only in the sense that it does not add to the CO2 in the atmosphere.
Green Energy is energy that can be extracted, generated, and/or consumed without any significant negative impact to the environment. The planet has a natural capability to recover which means pollution that does not go beyond that capability can still be termed green.
Green power is a subset of renewable energy and represents those renewable energy resources and technologies that provide the highest environmental benefit. The U.S. Environmental Protection Agency defines green power as electricity produced from solar, wind, geothermal, biogas, biomass and low-impact small hydroelectric sources. Customers often buy green power for avoided environmental impacts and its greenhouse gas reduction benefits.

[BBC Technology Documentary] Renewable Energy - NEW Science Documentary HD
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.[2] Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.[3]
Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. Both, modern renewables, such as hydro, wind, solar and biofuels, as well as traditional biomass, contributed in about equal parts to the global energy supply. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.[4]
Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.[5] In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power.[6] At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.[7]
While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development.[8] United Nations' Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity

Nonrenewable and Renewable Energy Resources.?
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.

Renewable and Nonrenewable Energy
The sources of energy which can be regenerated are called as renewable resource of energy. Renewable resources of energy include those source supply is unlimited. A natural resource is known as a renewable resource. Because it can be replaced by natural methods at a rate quicker than its rate of expenditure by people. These are otherwise called as inexhaustible source, because their reserves can supply is unlimited.
If any energy resource is used faster then it will be replaced by another. For example coal takes millions and millions of years to form and will eventually run out. This is called non-renewable energy source. Non renewable resources are finite in quantity and are being used faster than its ability to regenerate itself. Examples of non-renewable resources include metallic minerals, fossil fuels and nuclear power.

Water — so essential to us all, and yet it still has the potential to further impact our lives in important and positive ways. Hydroelectricity goes by many names — “hydroelectric energy,” “hydropower,” or just plain “water power” — but don’t let that trip you up. It all boils down to harnessing the force of moving water. In this video, you’ll learn interesting hydropower facts and how water power works. Isn’t it amazing how something as simple as water can offer us clean, renewable energy to power our homes, businesses and communities sustainably? We certainly think so!
Transcript:
Renewable Energy 101
Water covers 71% of the Earth's surface and is vital to our daily lives. It can also be a clean, renewable, reliable source of electricity.
Hydroelectric energy comes from capturing the force of moving water that's in our Earth's rivers and oceans. We do this by using the movement of the water to spin hydraulic turbines. That generates kinetic energy, which is converted to electricity through a generator and then sent to the power grid.
Most hydropower is generated from dams built on rivers and streams, often where there's a big drop in elevation so gravity can help us out. Dams block the water's natural flow and force it through a large pipe with the turbine and generator before releasing it back into the stream on the other side of the dam. Today, we know that dams — most of which were built before the 1960s here in the U.S. — can disrupt river ecosystems. There haven't been many new hydro plants built in the U.S. in a few decades, but some existing dams are beginning to be tapped for their electricity-generating potential, and existing hydro facilities are being upgraded to be less harmful to plants, fish and wildlife. This helps us get the electricity we need by protecting the natural environment around us. Now that's a win-win!

With technological progress, our demand for energy increases day by day. Our lifestyles are also changing, we use machines to do more and more of our tasks. Our basic requirements are also increasing as industrialization improves our living standards. As our demand for energy increases, we need to look for more and more sources of energy. We could develop the technology to use the available or known sources of energy more efficiently and also look to new sources of energy. Any new source of energy we seek to exploit would need specific devices developed with that source in mind. We shall now look at some of the latest sources of energy that we seek to tap, and the technology designed to capture and store energy from that source.

A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are almost always conserved.
In contrast, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within time frames meaningful to humans.
Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in Earth's crust, and their extraction by humans only occurs where they are concentrated by natural geological processes (such as heat, pressure, organic activity, weathering and other processes) enough to become economically viable to extract. These processes generally take from tens of thousands to millions of years, through plate tectonics, tectonic subsidence and crustal recycling.
The localized deposits of metal ores near the surface which can be extracted economically by humans are non-renewable in human time-frames. There are certain rare earth minerals and elements that are more scarce and exhaustible than others. These are in high demand in manufacturing, particularly for the electronics industry.
Most metal ores are considered vastly greater in supply to fossil fuels, because metal ores are formed by crustal-scale processes which make up a much larger portion of the Earth's near-surface environment, than those that form fossil fuels which are limited to areas where carbon-based life forms flourish, die, and are quickly buried.
Natural resources such as coal, petroleum (crude oil) and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. Eventually it is considered that fossil-based resources will become too costly to harvest and humanity will need to shift its reliance to other sources of energy such as solar or wind power, see renewable energy.
An alternative hypothesis is that carbon based fuel is virtually inexhaustible in human terms, if one includes all sources of carbon-based energy such as methane hydrates on the sea floor, which are vastly greater than all other carbon based fossil fuel resources combined. These sources of carbon are also considered non-renewable, although their rate of formation/replenishment on the sea floor is not known. However their extraction at economically viable costs and rates has yet to be determined.
At present, the main energy source used by humans is non-renewable fossil fuels. Since the dawn of internal combustion engine technologies in the 19th century, petroleum and other fossil fuels have remained in continual demand. As a result, conventional infrastructure and transport systems, which are fitted to combustion engines, remain prominent throughout the globe. The continual use of fossil fuels at the current rate is believed to increase global warming and cause more severe climate change.
In 1987, the World Commission on Environment and Development (WCED) an organization set up by but independent from the United Nations classified fission reactors that produce more fissile nuclear fuel than they consume -i.e. breeder reactors, and when it is developed, fusion power, among conventional renewable energy sources, such as solar and falling water. The American Petroleum Institute likewise does not consider conventional nuclear fission as renewable, but that breeder reactor nuclear power fuel is considered renewable and sustainable, before explaining that radioactive waste from used spent fuel rods remains dangerous, and so has to be very carefully stored for up to a thousand years. With the careful monitoring of radioactive waste products also being required upon the use of other renewable energy sources, such as geothermal energy.

Importance of Renewable Energy and Types of Renewable Energy
RENEWABLE ENERGY http://bit.ly/2Ng8DIl
Renewable energies are sources of clean energy, inexhaustible and increasingly competitive. They differ from fossil fuels mainly in their diversity, abundance and potential for use anywhere on the planet, but above all because they do not produce greenhouse gases, which cause climate change, or pollutant emissions. Their costs are also declining and at a sustainable pace, while the overall trend of the cost of fossil fuels goes in the opposite direction despite their current volatility.
The growth in clean energy is unstoppable, as reflected in the statistics produced in 2015 by the International Energy Agency (AIE): they accounted for almost half of all the new generation capacity installed in 2014, when they were the second largest source of electricity largest in the world, behind coal.
According to the IEA, global electricity demand will have increased by 70% by 2040, its share of final energy use will increase from 18 to 24% during the same period, driven mainly by the emerging economies of India, China, Africa and Middle East. and Southeast Asia.
Why do we need to use renewable energy? http://bit.ly/2Ng8DIl
Since then, the shares of U.S. energy consumption from biofuels, solar, and wind energy have increased. ... Renewable energy plays an important role in reducing greenhouse gas emissions. Using renewable energy can reduce the use of fossil fuels, which are major sources of U.S. carbon dioxide emissions.
What are the advantages of renewable energy? http://bit.ly/2Ng8DIl
One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.
Why is it better to use renewable energy?
A wealth of alternative energy sources, from wind and solar energy to hydroelectricity and biomass fuel offer a way to power homes, vehicles or businesses without using fossil fuels. That means renewable energy sources can help reduce the amount of greenhouse gas emissions we put into the air.
Why do we need energy? http://bit.ly/2Ng8DIl
Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body's most important nutrient, helps facilitate the chemical reactions that produce energy from food
Why solar energy is important?
Solar Is Clean and Safe. Solar is a safe alternative which can replace current fossil fuels like coal and gas for generation of electricity that produce air, water, and land pollution. ... Use of solar energy will eliminate these unsafe, unclean consequences from using conventional fossil fuels.
Why is energy so important? http://bit.ly/2Ng8DIl
Energy, defined as the capacity for work. It is almost the cause of so many things going on around us. When we eat, our bodies stored energy through the food and this energy turn into for allowing us to do action in any business. ... Energy is very important for world also our daily life
Why is it important to save energy?
It's a no-brainer: When we use less energy, we save precious natural resources and cut down on pollution. ... So, energy efficiency helps us keep more resources on the earth longer. Avoiding pollution: From power plants to cars, consuming energy can produce emissions that harm our environment.

The first episode of '10 or Less', an educational podcast series where I take a boring long chapter from a textbook and turn it into a video that's 10 minutes or less.
Today's material is adapted from the G. Tyler Miller book, "Living in the Environment", suggested by CollegeBoard as one of their textbooks for the AP Environmental Science test.
This video was originally intended for my Environmental Science class at Woodland High School, but feel free to use and share the video with everyone else studying environmental science. The slideshow was created with Prezi!
